PATENT J. F. BLACK AND W. L. BLACK, OF LANCASTER, ILLINOIS.

IMPROVEM ENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 32,958, dated July 30,1861.

To all whom it may concern Be it known that we, J. F. BLACK and WV. L.BLACK, of Lancaster, in the county of Cass and State of Illinois, haveinvented a new and Improved Gang-Plow; and we do hereby declare that thefollowingis a full, clear, and ex act description of the same, referencebeing had to the annexed drawings, making a part of this specification,in which Figure 1 is a side elevation of our invention; Fig. 2, a planor top view of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to an improved gangplow,which is designed to bedrawn bya team.

The object of the invention is to facilitate the turning of theimplement, and at the same time obtain a device which will perform itswork: in a thorough manner. To this end the parts of the plow are soarranged that the plowbeams and plows may be elevated and the plowsraised by the driver above the surface of the ground with the greatestfacility, and the plow-beams, when the implement is at work, renderedcapable of being secured to the draft-pole, or connected thereto in sucha manneras to prevent the casual rising of the plows from the earth.

Toenable those skilled in the art to fully understand and construct ourinvention, we will proceed to describe it.

A represents an axle, and B B wheels thereon.

O O are two parallel bars, which are permanently attached to the axle A,the front ends of the bars 0 projecting a short distance in front of theaxle. The bars C 0 form plowbeams, each beam having an inclined foot, D,attached, to which a turn-plow, E, is secured, one plow being in advanceof the other, and the back one turning a slice, which adjoins or laps onthe one turned by the front share.

Between the front ends of the bars or beams O O the draft-pole F issecured by a bolt, G;

and H H are two uprights, which are secured to the front parts of thebars 0 G and support the drivers seat I.

J is afoot-board, the back end of which is secured between the uprightsH H, and is properly supported by uprights K K, which are attached tothe front ends of the bars 0 O one to each.

L is a toggle, the lower end of which is attached to the back part ofthe draft-pole F, and the other end attached to the under side of thefront part of the foot-board J, as shown clearly in Fig. 1.

M is a rod, the front end of which is attached to the toggle, and theback end to the lower part of a lever, N, which is secured to theright-hand upright II, said upright having a catch, a, at its upper endto hold the upper part of lever N in a backward position. WVhen theupper end of lever N is held in a backward position, the toggle L iskept perfectly straight, and the foot-board J is prevented fromapproaching the draft-pole F, and the plows E E are thereby retained inthe earth and made to perform thorough work. On arriving at the ends ofthe furrows, where it is necessary to turn the plow, the driver throwsforward the upper end of lever N and at the same time throws his weightforward on the foot-board J, and the plows will consequently be elevatedabove the surface of the ground, the toggle L by this movement drawingdown the foot-board J, as shown in red, Fig. 1. In order to adjust theplows in the ground, the driver draws back the upper end of lever N, andat the same time throws his weight back on seat I.

In order to regulate the depth of the penetration of the plows E, thearms of the wheels 13 B may be attached to plates at a, between whichthe axle A may be adjusted higher or lower, as desired.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The toggle L, with lever N attached, draftpole F, foot-board J, driversseat I, plowbeams O G, and axle A, combined and arranged to operate asand for the purpose herein set forth.
